ImportError: No module named collections

I’m trying to install the pymssql module: pip install pymssql --> “ImportError: No module named collections”. How can I fix this?

You need a file named (two underscores on each side) in every folder in the hierarchy. This is what python looks for to know that it should access a particular folder. The files are meant to contain initialization instructions but even if you create them empty this will solve it. To get rid of this error “ImportError: No module named”, you just need to create in the appropriate directory and everything will work fine.
